I missed that you were using b111 earlier. That's probably a large part of the problem. There were a lot of performance and reliability improvements between b111 and b134, and there have been more between b134 and b148 (OI) or b151 (S11 Express). Updating the host you're receiving on to something more recent may fix the performance problem you're seeing. Fragmentation shouldn't be to great of an issue if the pool you're writing to is relatively empty. There were changes made to zpool metaslab allocation post-b111 that might improve performance for pools between 70% and 96% full. This could also be why the full sends perform better than incremental sends. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
